[Plugin: WP-Logs] not sure where to put the code?

so in the readme file, it states to put this

$EventLog = new EventLog(array(
	'event' => 'Login Successful',
	'text' => var_export($_REQUEST,1)
));

in my theme/plugin code.

where in the theme/plugin code? i attempted to add it to the page.php just on a lark, and it broke things and had to be removed; it gave me a syntax error. am i supposed to wrap those lines in <?php> tags? i am php-retarded, i have no idea what i’m supposed to do with this information.

thanks.
